ABSTRACT:
A solar concentrating collector includes corrugated board parabolic support segments with flexible strips and side tabs over the cut edge to support a laminate with reflective coated film. The reflector assembly has supporting arms and pivots about a heat absorbing conduit secured to vertical extensions of adjacent stationary posts. Selected external surfaces are weatherproofed. The conduit includes vacuum insulators and means to isolate conduit from insulator expansion. Upper arms support pulleys and cable take-ups for continuous collector position changes. Cross members of the extended post secure the fixed conduit, and at a higher level, a programmable drive to rotate two cable capstans for cables that pivot two adjacent reflector assemblies. Other embodiments include triangular or square fluid conduits with planar surfaces for photovoltaic cells and a modified reflective surface to disperse solar rays into a band of reflected sunlight directed to photocell areas.
